The Texas Instruments UCC3804DTR is an obsolete integrated circuit from the UCC280x family of high-speed, low-power PWM controllers. It is designed for fixed-frequency current-mode switching mode power supplies, requiring minimal external components.
This controller operates at frequencies up to 1MHz and supports a 1A totem-pole output. Key electrical specifications include a supply voltage range of 8.3V to 12V, a maximum duty cycle of 49%, and a typical operating supply current of 500µA. It also features internal soft start and leading-edge blanking of the current-sense signal.
The UCC3804DTR is housed in an 8-SOIC surface-mount package. It is specified for an operating temperature range of -40°C to 85°C. While the part is marked as obsolete, its design is similar to the UCx84x family, offering integrated control and drive components for power supply applications.
This component is suitable for various off-line and DC-to-DC power supply designs where a compact and efficient PWM controller is required. Its features make it a choice for applications needing precise current-mode control.
